R5F64189PFB芯片概述:
  The M16C/6N Group (M16C/6N4) of MCUs are built using the high-performance silicon gate CMOS processusing the M16C/60 Series CPU core and are packaged in 100-pin plastic molded QFP and LQFP. TheseMCUs operate using sophisticated instructions featuring a high level of instruction efficiency. With 1 Mbyte ofaddress space, they are capable of executing instructions at high speed. Being equipped with two CAN(Controller Area Network) modules in the M16C/6N Group (M16C/6N4), the MCU is suited to drive automotiveand industrial control systems. The CAN modules comply with the 2.0B specification. In addition, this MCUcontains a multiplier and DMAC which combined with fast instruction processing capability, makes it suitablefor control of various OA, communication, and industrial equipment which requires high-speed arithmetic/logic operations.
  Watchdog Timer Reset
  Where the PM12 bit in the PM1 register is “1” (reset when watchdog timer underflows), the microcomputer initializes its pins, CPU and SFR if the watchdog timer underflows. Then the program is executed
  starting from the address indicated by the reset vector.
  At watchdog timer reset, some SFR’s are not initialized. Refer to “SFR”. Also, since the PM01 to PM00 bits in the PM0 register are not initialized, the processor mode remains unchanged.
  Where the CPU clock source is changed from the On-chip Oscillator to the main clock, change the operation mode to the medium speed mode (divided by 8 mode) after the clock was divided by 8 (the CM06 bit of CM0 register was set to “1”) in the On-chip Oscillator mode.
  - High-speed Mode
